Here is the press release Sabra issued with more details about the recall:

"Sabra Dipping Co., LLC announced that it is voluntarily recalling approximately 30,000 cases of its Classic Hummus due to possible contamination with Listeria monocytogenes. This measure is limited to five SKUs of Classic Hummus sold nationwide. To date, no other Sabra product is affected by this recall.

Listeria monocytogenes is an organism, which can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Although healthy individuals may suffer only short-term symptoms such as high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea, Listeria infection can cause miscarriages and stillbirths among pregnant women.

To date, there have been no reports indicating that these products have caused any illness.

The products being recalled are listed below and were distributed to retail outlets, including food service accounts and supermarkets, in the U.S. Consumers can find code and use by dates on the top of each package.

The potential for contamination was discovered when a routine, random sample collected at a retail location on March 30th, 2015 by the Michigan Department of Agriculture and Rural Development, tested positive for Listeria monocytogenes.

Consumers who have purchased any of these products are urged to dispose of or return it to the place of purchase for a full refund. Consumers with any questions may call toll free 1-888-957-2272, Monday – Friday 9:00AM to 4:30PM Central Time."
